I have went directly to the site to download install_flashplayer11x64_mssd_aih, go to install, it gets to 99% and then blue screen.

I have used firefox to go to a flash site, it says I am missing supporting plug ins, so I try and install, it tells me has to be manually installed, links to adobe site, install, close firefox, 99% then blue screen.

I also used internet explorer to try and install, but same steps, tries to install plugin, then tells me must be done manually, download the install file, install, blue screen.

So I saved that to a text file, and followed it 100%, verified all files were deleted, restarted back into windows, installed active x plugin (install_flash_player_ax_64bit) it worked,

then I went to install the other file install_flash_player_64bit, it got to 100% then crashed my computer again. but this time, no blue screen, just an endless loop.. I couldn't control alt delete or anything, waited about 3 mins to see if it came back but just sat frozen until I force restarted by holding power button.

Now that Flash Player for Internet Explorer is installed, can you view flash videos with it?

I don't use Firefox, so I don't know for sure what is going wrong. However, the latest Firefox is version 11.
